[REQ][CSHARP][GENERICHOST] Support stream for binary response

[alec-petersen]

Fixes #21676

Creates a switch statement on the HttpStatusCode to determine how to create the ApiResponse.

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Very cool, thanks! Can you add something to the petstore and build the samples?

[alec-petersen]

@devhl-labs Thank you! Looks like I got some work to do for backwards compatibility.

@alec-petersen thanks for the pr

@devhl-labs is this PR ready? if yes, i will get it merged asap

[devhl-labs]

I guess you want the first response which is a binary, but i don't think this first will filter the way you want.

[alec-petersen]

How do ya mean? And yeah the goal here is just to add the section if there is a binary response, there may be a better way of accomplishing that in a more mustachey way haha

[devhl-labs]

I think the first will get rendered every time. Pretty sure we can only use first like this on arrays.

[devhl-labs]

There is a first lambda besides the one you used here but it requires a two space delimiter which is not ideal for a multiline string.

[alec-petersen]

It seems to have the effect I intended, I'd need to understand the failure scenario maybe.

[devhl-labs]

Lets just send it. My concern can be fixed in a another pr.
